It occupies the outermost stratum and the posterior layer at the tip of the alpha and beta lobes (Tanaka et al., 2008). In the shaft region of the alpha lobe, alpha/beta posterior Kenyon cell form mesh-like arrangements, with one or two nodes where axons appear to gather. In the pedunculus, their axons form several bundles, which run through the outermost layer of the central zone. They are the first-born alpha/beta Kenyon cells (Aso et al., 2014). There are around 60-90 of these neurons in each hemisphere (Aso et al., 2014; Takemura et al., 2017; Li et al., 2020). They receive visual input in the dorsal accessory calyx, but this is mainly from local visual interneurons, rather than visual projection neurons (Li et al., 2020).
